The CW's interconnected DC universe continues to expand this fall, as Legends of Tomorrow joins Arrow and The Flash. While this one is a directly linked show, originally considered an Arrow spin-off, there's a fourth series that could also be joining this multi-series: Supergirl!
The upcoming series featuring a Kara Zor-El premiers on CBS this October, and while there are no promises of a crossover with the other DC shows, there has been plenty of speculation about it happening down the line.
For one thing, CBS owns the CW, clearing up any issues with sharing the rights to the characters. Not that this would necessarily be an issue anyway, if the recent news that Constantine would be appearing on Arrow, despite being on NBC before it was cancelled. Supergirl also shares a producer with Arrow and The Flash in the form of the talented Greg Berlanti, who made it clear in an interview with Variety that he would love to see the shows connect.
"I always approach the shows as a fan first, so I would love to see (a crossover). I think in success, all things are possible. But there’s a lot that would have to happen before everybody might say yes to that."
While it originally seemed that this was just a dream, Entertainment Weekly has now revealed that we are going to see a little bit of a crossover - in promotions for the shows.
(CBS Chairman) Nina Tassler: "We have not had conversations about the crossovers, but we are doing crossover promotions, so we will see that with the promotion crossovers, but not in terms of the characters."
This could mean simply that Supergirl will appear within the same promo material as Arrow and The Flash, in something like this recent video for the CW's fall lineup.
However, that seems thoroughly unremarkable, and I doubt that it would even be mentioned when discussing crossover potential.
Far more likely, as far as I am concerned, is seeing something along the lines of the cage-fighting cross-promo that came out for Arrow and The Flash. How amazing would it be to see the expanded teams from Legends of Tomorrow and Supergirl join our heroes in the ring?
That said, the phrase "not in terms of the characters" is a little confusing - a mash up of the titles? A promotional video showing a map of the US with the various super-locations pinpointed? There are definitely a few other options available.
Whatever happens with this new promotional crossover, it seems to suggest that the idea of a link between the shows is not off the table entirely. There may still be some issues with involving Supergirl in the Arrow/Flash-verse, but we can continue to hope!
Supergirl comes to CBS October 26th.
